`"sULKY-PLow.`

SPECIFICATION forming part of Letters Patent No. 224,713, dated February 1'7, 1880.

` l Applieationled December 3,1879.

` To all whom it mayconcewt Be it known that I, JAKoB FRIEDRICH MU'NZ, of Delaware, in the county of Delaware and State of Ohio, have invented certain `new and useful Improvements in Sulkies for Plows andCultivators; and I `do hereby declare that the following is a full, clear, and exact description of the invention, which `will A enable others skilled in the art to which it api This invention has for its object to furnish a convenient, cheap, and substantial sulky for I will first describe my invention and then point it out in the claims.

In the drawings, Figure 1 is a side elevation. i Fig. 2 is a section on line .r fr, Fig. l. Fig. Bis a section on line y y, Fig. l. Fig. 4t

is the clevis employed for attaching lthe cultivator-beam to the sulky-'frame, and Fig. 5 shows the method of adjusting the tongue to `regulate the side draft.

The main frame is composed of two paral-` lel longitudinal side bars, a a, rear cross-bar, a', and arch a2. The arch a2 is made rectangular in form, and is secured near the center of the side bars, a a, so that the ends of the latter project forward to provide facilities for attaching other mechanism hereinafter `dey scribed.

`is placed downward, and is constructed and arranged to cross thearm a2 of the arch with its central point liush with the lower end thereof, as shown.

The lower end of the arm a2 is rigidly securedto the central point of the support a, thus forming with said arch, cross-bar a', and side bars, a, a very strong and durable frame.

I) is a vertical bar, placed against the vertical arms a, and provided with sleeves or loops b5, which t around the said :arms a3 and permit the bar b to be readily slipped up or down.

On the lower end of the bar b I X the spindle which carries the wheel b', and on its upper end I form a loop or hook, b2, which engages on the lever b3, by which the wheel is raised or lowered. i

The end of the lever b3 is pivoted to the rear wing or arm of the brace wgand is slightly` bowed upward fromits pivotal point to the hook b2, so that it will readily slide through the latter when employed in elevating the wheel. The free end of the lever b3 is held in any desired position by ratchet-teeth b4, fixed on the side of the forward arm of the brace a4.

c is a yoke or hinged bail,which supports the forward end of the beam when the sulky is employed for operating turn-plows. Thef yoke has its ends pivoted in the lower end of the brace a4 forward of the central vertical arm a3 of the arch a2. It is made in the form of a double crank, as shown, so lthat it may be turned up or down, as may be required. The yoke is operated and controlled by a lever, o', pivoted to the side bar, a, and the connecting-rod c2. The lever is held in any desired position by the curved ratchet-bar c3.

d is a yoke similar in form to yoke c, and it is journaled in the brace in rear of the vertical arm a3, and in the same plane with the `journaled ends of the forward yoke, c. The rear yoke is raised or lowered and controlled by the lever df, pivoted to the bar ain rear of the drivers seat, connecting rod d2 and ratchet d3, arranged as shown.

The arrangement of yokes or frames c' and d with their centers of motion in front Vand in rear of the vertical axial plane of the wheels enables me to employ a 'much shorter frame, and one which will yield quicker to the action of the lever, and which will have greater strength with less weight of material than 'is found in machines of ordinary construction.

e represents a beam of a plow or cultivator, which is secured to the yokes o and d by -the clevises or loops f and c. These loops or clevises are held in position so that they may be adjusted laterally in different positions IOO along the yokes, thereby permitting the lateral movement and adjustment of the beam e.

The forward loop or clevis, f, has a hinged or swinging movement, and binds and holds the beam betweenlits outer bar, f3, and the yoke c. By turning it into a vertical position the beam .may be slipped forward or back, as desired.

The beam e may be placed above or below the yokes, or one of the latter may be placed above and the other below the beam. The clevises may be reversed to suit the changed positions of the beam.

g is a drag secured on the side of the rear yoke, d, next the unplowed land. It may be removed at pleasure, and its use is to draw Weeds, 85e., into the open furrow to be covered by the earth turned from the next cut furrow.

h is a rotating head-block, (of whichv there are two, arranged similarly and on opposite sides of the sulky-frame, and on the inner sides of the lower ends of the side arms, a3,) which is provided with suitable end pins or gudgeons, one of which is journaled in one of a series of holes, t', formed in the bow or lower end of the brace a4.

The opposite gudgeon is journaled in the lower end of a brace, h', which is placed on the inner side of the side arm, a3, and which has the upper end secured by, and so that it turns on, a pin fixed near and projecting from the upper end of the inner side of the arm a3 of the arch a.

The series of holesil is in a circle concentric with the curve described by the lower end of the brace h', as the latter is turned forward or back in the adjustment of the head-block h. The head-block h is provided with laterallyprojecting pins or other suitable means whereby the end of the plow or cultivator beam h3 may be readily attached thereto.

The beam of the cultivator or shovel-plow rests on the rear bail or yoke, d, by which it is raised or lowered in same manner as the rear end ofthe beam c is raised or lowered. The cultivator-beam h3 may be left free to swing laterally on the head-block h, or it may be iixed to the yoke d by the clip e in the same manner as the beam e is fixed. By this arrangement the two cultivators or shovelplows which may be employed on the sulky can be set to run closer together or wider apart, as may be desired, by sliding' the clips e' one way or the other along the bail.

In Fig. 4 is shown the form of clevis which I employ on the ordinary iron-beam cultivators orshovel-plows, by which the latter are attached to the head-block h. The clevis has an under hinged jaw, k7, and a iiat connecting-bar, h6, which afford ready means of attachment.

It will be seen that the head-block It may be set forward or back of, or in the same vertical plane with, the arm a3 of the arch a2, which enables me to give to the cultivator a longer or shorter coupling, when desired, or to place the bearing of the end of the beam in front or in rear of the axial line of the wheels.

-Hooks h8 are axed to the rear ends of the side bars, a, on which to hang .the shovelplows or cultivators, in usual manner.

In Fig. 5 is shown the manner of attaching the tongue k so that it can vbe turned or moved laterally for purposes of adjustment to regulate side draft. The tongue is held by loops lo' 7a2 to the cross-bar a and arch a2, so that its forward end may be turned to one side or the other without moving the rear end; or both ends may be moved equally to one side, as indicated in dotted lines.

The sulky hereinbefore described may be used interchangeably, either for a turn-plow, or for a shovel-plow, or for a cultivator. The removal of one of these implements and the attaching of one of the others are readily and quickly done.

I am aware that double yokes or frames for supporting the plow-beam have been heretot'ore employed, and that sulky-wheels have been attached to bars with capability of a vertical adjustment.

The seat l is attached so that it may bemoved and fixed either on thc front or rear of the sulky-frame.

Having thus described my invention, what I claim, and desire to secure by Letters Patent is- 1. The combination, with the arch a? and the brace or frame a4, having the series of holes i in its lower end, ofthe swing-brace h', having its upper end pivoted near the upper end of the inner side of the vertical arm a3 ot' the arch a2, the head-block h, journaled in the lower end of the brace h and in one of holes i of frame a4, and yoke or bail d, substantially as set forth.

2. In a sulky for plows and cultivators, the combination of the side bars, a, the arch a2, the braces or frames a4, having their ends secured to the bars a a in front and rear of the vertical arm co3 of the arch a2, and having-their lower or bow ends secured to the lower ends of the vertical arms a3, the yokes c and d, one of which is journaled to the lower end of the brace a4 in front ofthe vertical axial plane of thewheel, and the other journaled to said brace in rear of said axial plane, and the rotating head-blocks h h, all arranged to operate substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JAKOB FRIEDRICH MUNZ.
